Overview
Since the turn of the century, Thomas & Betts has been a recognizedleader in electrical fittings. Industry standards such as Chase® Nipples and Erickson® Couplings were introduced by Thomas & Betts and are still registered trademarks. This leadership continues. Here’s why...
The Complete Product Line
High-Performance Products
Quality and performance result when engineering design skills are combinedwith the manufacturing technologies required to produce them. The Thomas & Betts Fittings in this section are produced from many materials and by many manufacturing methods, each carefully selected for its end usesuitability. This combination gives you the reliable performance you expectfrom Thomas & Betts Raceway Fittings.
Innovative Designs
The real test of product design of electrical fittings lies in two areas: Job-suited installation and life of the job reliability. Thomas & Betts Fittingsprovide both because we listen. We listen to problems and suggestions from the field. Most of the products in this section result from the goodsuggestions of knowledgeable electrical people. Many were customer specials to solve particular installation and performance problems. You can benefit from their experience.
Lower Installed Cost
It is a function of purchase cost, availability, installation advantage and performance. Lower installed cost comes in every carton of Thomas & Betts Raceway Fittings.
Approvals and Listings
Electrical raceways require accessory fittings that provide the mechanicalstrength, ground continuity and environmental integrity of the system. As newraceways have been introduced, Thomas & Betts engineers have designedfittings that meet the requirements of the National Electrical Code® as well as the listing requirements of the Underwriter’s Laboratories and the CanadianStandards Association. You can use Thomas & Betts Fittings with confidence.

DURA-PLATE® Corrosion-Resistant Fittings have a T&B plating processthat provides excellent corrosion resistance on threaded steel andmalleable iron fittings for use in harsh environments.
DURA-PLATE® Corrosion-Resistant Fittings utilize an electro-platingprocess that ensures a uniform thickness of protective material overthe entire part. Conventional hot dip coatings deposit an uncontrolledbuildup of material on the part, especially in threaded areas. Thisexcess buildup must be removed to enable mating parts to function.
The process of removing this buildup in the threads in turn damagesthe coating and compromises the effectiveness of the protection.
An additional drawback of hot dip coating is that the lower ductility of the alloyed interface layer that is formed during the hot dip process can cause spalling if the item is deformed after coating.
In addition to the uniformity of the coating, the distinctive gold color of the plating enables immediate recognition that the part has beenprepared for exposure to harsh environments and confirms the extraprotection by visual inspection.
DURA-PLATE® Corrosion-Resistant Fittings have been subjected to salt spray tests conducted according to ASTM Specification B-117.The results of Corrosion-Resistant Fittings tests, along with galvanizedparts, appears below:

Blackjack® — Grounding Bushing
The Blackjack® Grounding Bushing never has to be threaded onto a conduit. It is simply placedin position on either a threaded or non-threadedrigid or IMC conduit, with the grounding lug inperfect position to accept the grounding wire —even in tight installations.
It’s as simple as one, two, three!
Compare the installation with conventionalbushings that must be threaded onto theconduit. In tight areas, you may have to remove
the grounding lug, keep up with the loose partsand then reattach the lug. Then you still have to twist and turn the bushing to get the lug in position to accept the grounding wire.
The Blackjack bushing does away with theseneedless delays for good, making it the idealgrounding bushing — and the only logicalchoice for small spaces, corners and multipleconduit runs. And, because the grounding lug is an integral part of the bushing, it's designednot to fall off or get lost.

The Blackjack® bushing providessuperior ground continuity.The design of the Blackjack bushing has an integral, cast-on grounding lug for betterground continuity. This means that the Blackjack bushing stands up to intense loads.
Secure grip forms lasting bond.The Blackjack bushing’scone-point mounting screwbites securely into boththreaded and non-threaded rigid conduits. And theBlackjack bushing’s nylonlocking patch is designed to prevent the screw fromloosening due to vibration.
Reduce inventory.Because the Blackjack Grounding Bushing is designed for threaded and non-threadedconduits, and the ground lugs are designed tohandle an extended range, the number of partsin inventory is reduced by up to two-thirdswithout losing any application coverage.

ApplicationEYD drain and inspection sealing fittings:
• Restrict the passage of gases, vapors or flames fromone portion of the electrical installation to another atatmospheric pressure and normal ambient temperatures
• Limit explosions to the sealed-off enclosure• Prevent precompression or “pressure piling” in conduit
systems. Drain sealing fittings are installed in verticalconduit runs and at low points in conduit systemsto prevent accumulation of condensate above seal
FeaturesEYD drain sealing fittings include:
• Drain to provide continuous, automatic drainage of condensate
• Large openings with threaded closures to provide easy access to conduit hubs for making dams
• Integral bushings to protect conductor insulation from damage
• Tapered-tapped hubs to ensure ground continuityStandard Materials• Bodies, and inspection or drain covers — Gray iron alloy

Application
The Thomas & Betts Universal drain/breather fittings can be used as drains or breathers dependingon the installation.• To use as a drain, the product must be installed in the bottom of the enclosure or the
lowest point where an NPT threaded opening exists. It can also be used in a seal fitting ora “T” conduit body. These must be in a lower section of the conduit system. This will enablemoisture inside the conduit system to drain out
• To use as a breather, installation should be done at the top of an enclosure or in uppersections of conduit systems. This will permit air exchange and keep moisture accumulationinside the conduit system to a minimum, Thomas & Betts recommends the use of at least2 devices (one drain and one breather) for maximum efficency
Application• Limits flames and/or explosions to area within electrical
system where they originate
• Limits pressure piling
• Required by NEC for conduit systems in hazardouslocations 18" from an enclosure housing a heatproducing or arcing device; on 2" and larger systemthat enters an enclosure containing splices; whereverconduit leaves a Class I, Division I area and entersa non-hazardous area
• Precision cast and machined surfaces permitsafer wire pulling
• Precision NPT threaded hubs enable trouble-free field installation for rigid or IMC conduit
• Large opening provides maximum working room forcreating dam and seal pouring to speed up installation
• Compact design permits close construction of parallel conduit runs

T&B Red•Dot® sealing cement is used for making seals in sealing fittings. The insulationin the conductors sealed in the cement may be approved thermoplastic or rubber, withor without lead covering. The sealing cement should not be used for insulating.
CharacteristicsT&B Red•Dot® sealing cement is not affected by gasoline, alcohol, acetone, ether, naptha, petroleum, benzol or lacquer solvent.
Preparation(1) Use a clean mixing vessel for each batch.
(2) Thoroughly mix powder before adding water.
(3) Do not use if temperature is below 40° F.
(4) Mix 1 part water to 2 parts cement.
(5) Allow cement to set for 72 hours before use.
Standard Dams(1) Push the conductors away from the filling opening and force them apart so that they
do not touch each other or the walls of the fitting or conduit along their length. If theconductors do touch, the sealing cement will not form a closed path between them.
(2) Force the packing fiber between each conductor and the inside walls. Be sure that thedam is strong enough and tight enough to prevent the considerable weight of the fluidsealing cement from seeping out.
Pouring(1) Pour the mixed cement into the fitting slowly so as not to trap air in the seal.
(2) Replace the close-up plugs to ensure that they engage not less than 5 full threads.

Good connections are one of the most important aspects of electrical work. Mechanicsknow how much downtime is caused when fluids or oils leak into the raceway system orwhen looking for a weak link in a ground system caused by a high resistance connection.Mechanics also know how much time is spent keeping contacts, switches, lugs and otherconnectors clean or replacing parts because of “green scourge” buildup. Thomas & Bettshas the solution to improve connections made in thousands of electrical and racewayinstallations made each day by electricians everywhere.
Kopr-Shield® compound is a unique homogenized blend of pure, polished colloidal copper,rust and corrosion inhibitors that simultaneously protects, lubricates and enhances theconductivity of the mating surfaces to which it is applied. Extremely adhesive, Kopr-Shield®
compound flows smoothly into uneven contours and voids, making application easy,protection and lubrication complete and positive. A stable compound, it will not settle-out,thin, thicken, harden, or dry out under the most severe environmental conditions.
Kopr-Shield® Compound has excellent temperature characteristics — brushed on at -50˚ F to 250˚ F (other compounds either turn solid or run like water at these extremes).Even at 1800˚ F, Kopr-Shield® remains intact for short terms.
Kopr-Shield® Compound may be used to advantage in all electrical installations. When the environment is hostile to good electrical and mechanical connections,Kopr-Shield® Compound is a must!
Kopr-Shield® by Thomas & Betts meets the requirements of Section 300.6(A) in the 2002 NEC Code for Protection Against Corrosion.
“Where corrosion protection is necessary and the conduit isthreaded in the field, the threads shall be coated with an approved electrically conductive, corrosion-resistant compound.”
Use Kopr-Shield® Compound for Battery Lugs and Cables• Prevention of “Green Scourge” corrosion
• Reduction of resistance
• Ease of terminal installation and removal
Use Kopr-Shield® Compound for Raceways.• Lubrication — ease of assembly and disassembly
• Lubrication — easy installation and removal of fuses
Use Kopr-Shield® Compound for Wiping Contacts, Drum Switches and Slip Rings.• Prevention of galling, burning, pitting and discoloration
• Suppression of arching and dissipation of coronas

Jacketed Metal Clad Cable Termination Fittings
Jacketed Metal Clad Cable and Teck CableMetal Clad Cable (Type MC) Ref. NEC Article 334*“Metal Clad Cable Type MC is a factory assembly of one or more conductors,each individually insulated and enclosed in a metallic sheath of interlockingtape, or a smooth or corrugated tube.”
Metal Clad Cable Type MC is rated for use up to 5,000 volts. The NationalElectrical Code permits use of metallic sheath as an equipment groundingconductor.
Metal Clad Cables are available with a variety of phase conductor insulationssuch as crosslinked polyethylene, and silicone rubber ethylene propylene,depending on rated temperature of conductors and working potential.Metallic sheath can be of galvanized steel, aluminum, copper or bronze.A special outer covering such as PVC or Neoprene over metallic sheathis usually provided for environmental protection.
Metal clad cable is not permitted in locations where it could be subjectto physical damage. Metal clad cable can be used exposed, concealed, incable tray, in any approved raceway, and with minor exceptions in hazardouslocations. Type MC cable can also be used for services, feeders, branchcircuits, power, lighting, control and signal circuits.
Use of metal clad cable is permitted in wet locations, or where exposed todestructive corrosive conditions or can be directly buried in earth, concreteor exposed to cinder fills, strong chlorides, caustic alkalis, vapors, chlorineor hydrochloric acids provided the construction of cable, the conductorswithin the metallic sheath, the metallic sheath and protective cover overmetallic sheath comply with requirements enumerated in Sec. 334-3 ofthe National Electrical Code.
Bend radius restrictions are dependent on the size of the cable and thetype of sheath, i.e., smooth, interlocked armor, corrugated sheath or shieldedconductors and varies from 7 times to 15 times cable external diameter.
NEC Article 334 requires that approved fittings be used for termination.Where single-conductor cables carrying alternating current enter a ferrousmetal box or enclosure, procedures described in NEC Section 300-20 mustbe followed to reduce effects of heating due to induced currents. Theseprocedures include recommended arrangements of conductors, cutting ofslots in metal between individual conductor holes, passing of conductorsthrough insulating walls, or use of non-magnetic aluminum sheathed cableand aluminum terminating fittings.

Teck CablesTeck cable derived its name from one of its first users, the Teck-HughesGold Mines in Kirkland Lake, Ontario. Teck 90 is CSA Type designation.Trade designation of this cable is Armored Cable.
Teck cables up to 5,000 volt working potential are manufactured in accordancewith CSA Standard C22.2 No. 131 and are provided with a bare groundconductor and an optional outer jacket. Depending on phase conductor insulationthe cables are designated as Teck 90 (X-LINK) when insulation is cross-linked polyethylene and Teck 90 (EP) when insulation is ethylene propylene.Both cables are rated for 90° C service (dry location) and 75° C (wetlocations). When Teck cable is suitable for installation down to minus 40° Fthe cables are marked Teck 90 (X-LINK) minus 40 or Teck 90 (EP) minus 40.
Over 5,000 volts working potential Teck cables are manufactured in accordancewith IPCEA standards and are certified by CSA. Cables are provided with orwithout ground wire as required.
Teck cables with outer jacket may be used for exposed or concealed wiring inwet or dry locations, indoors/outdoors and in corrosive environments. Teck cablesare suitable for use in ventilated, non-ventilated and ladder-type cable troughs,in ventilated flexible cable ways in both dry and wet locations. Teck cable withouter jacket is suitable for direct earth burial and for Class II Division 2, ClassIII Division 1 & 2 hazardous locations per Canadian Electric Code.
Some of the features of Teck cable are its flexibility and ease of installation.Absence of dead air space within cable increases heat transfer and minimizecondensation. Overall protective covering provides good environmental protection.
Bend radii for permanent training during installation usually varies between7 times to 12 times the cable diameter depending on cable constructionand manufacturer’s recommendations. Larger radii bends are required forother conditions.
Section 12-3028 of the Canadian Electric Code requires that the terminatingfittings used must provide adequate strain relief to terminal connectionsand ensure electrical continuity without injury to non-metallic sheath.Continuity is mandatory whether or not the armor is used as a groundingconductor. Except for dry locations free from corrosive atmosphere, thenon-metallic jacket is not permitted to be stripped back to a point wherearmor is exposed after installation.
Where single conductor cables carrying 200 amps or more enter metalboxes through separate openings, certain precautions are required to preventoverheating of the metal by induction. Use of non-ferrous or non-metallic boxconnectors, locknuts and bushings and installation of non-magnetic panelinserts is suggested in the code.

Application• To connect and effectively bond electrical
metallic tubing to a box or an enclosure
• To provide a rain tight connection between tubing and the connector
• To couple ends of tubing
Features• Rugged all steel construction
• Rings designed to positively bond conduit to fitting; uniquelocknut design provides effective bond between fitting andbox or enclosure; ground continuity is ensured
• Nylon insulator firmly secured in place — protectsconductors, reduces wire pulling effort and prevents thread damage in handling
• Locknuts are designed with extended reach to lock fitting on to a thin box or an enclosure
• Locknuts tighten without deformation; will not vibrate loose
* Gaskets sold separately. In some jurisdictions, sealing gaskets are not required when installed in a threaded opening. Also, a connector assembled in the bottom of a box or enclosure may beconsidered by code “to be located (placed) so that water will not enter the enclosure at the knockout interface” (NEC 314.15 (A)). In this instance, the sealing O-ring may not be required. Consultwith the local authority having jurisdiction.

Metal Clad Cable, Armored Cable and Flexible Metal ConduitArmored Cable (Type AC) — Ref. NECArticle 320National Electrical Code defines type AC armoredcable as, “A fabricated assembly of insulatedconductors in a flexible metallic enclosure.”
ACT Indicates an armored cableemploying conductors havingthermoplastic (Type T) insulation.
AC Indicates an armored cableemploying conductors having rubber insulation of code grade.
ACH Indicates an armored cableemploying conductors having rubber insulation of the heatresistant (75° C) grade.
ACHH Indicates an armored cableemploying conductors having rubber insulation of the heatresistant (90° C) grade.
ACU Indicates an armored cableemploying conductors having rubber insulation of latex grade.
“L” Used as a suffix, it indicates that a lead covering has been appliedover the conductor assembly.
All armored cables may employ copper oraluminum or copperclad aluminum conductorswith the following sizes and are rated for 600 volts or less:
No. 14 AWG to No. 1 AWG Copper
No. 12 AWG to No. 1 AWG Aluminum or Copperclad Aluminum
Type AC cables except ACL carry an internalbonding strip of copper or aluminum in intimatecontact with the armor for its entire length.Armored cable can be used for both exposed or concealed locations. With lead-coveredconductors (Type ACL), the cable can beembedded in masonry or concrete and can beused in damp locations or where exposed to oil.
Armored cable is not permitted in locationswhere it will be subjected to physical damage or corrosive fumes. Armored cable cannot beused for direct burial in earth.
With minor exceptions, armored cable is alsonot permitted to be used in hoists or elevators,storage battery rooms, any hazardous locations,in commercial garages and in theaters or similarlocations.
Codes require that cable shall be supportedwith straps or staples without damagingconductors and also limit the minimum bendradius to 5 times the diameter of type AC cable.Certain precautions are prescribed in code wherecable is installed through joist rafters or similarwood members.
According to NEC 320 where armored cableis terminated, a fitting is required to protectconductors from abrasion. In addition, a bushingis required between the conductors and armor.Design of fitting has to be such that theinsulating bushing is visible for inspection.Bushing is not required with lead-covered cables when properly installed.

Non-Metallic Sheathed Cable Fittings
NOTE:
The materials herein, whether relating to the National Electrical Code, the Underwriters Laboratories, Inc. listing, to industry practice or otherwise, are not intended to provide all relevant information required for use and installation of our products. Refer to applicable codes, instructions and industry specifications prior to installation or use.
Non-Metallic Sheathed CableRef. NEC Article 336Code defines non-metallic sheathed cable as, “A factory assembly of two or more insulated conductors having an outer sheath of moisture resistant,flame retardant, non-metallic material.”
Non-metallic sheathed cable is constructed of insulated conductors (14 to 2 AWG Copper or 12 to 2 AWG Aluminum or Copperclad Aluminum),and an outer non-metallic sheath classified as Type NM or Type NMC.
Non-metallic sheathed cable is provided with or without a bare or insulatedequipment grounding conductor. Non-metallic sheathed cable is rated for 60° C service with voltage limitation of 600 volts.
Type NM — has flame-retardant moisture resistant sheath.
Type NMC — has flame-retardant, moisture-resistant, fungus-resistant and corrosion-resistant sheath.
Non-metallic sheathed cable is permitted by code to be used exposed or concealed in one, two or multifamily dwellings or other structures not exceeding three floors. Use of Type NM cable is restricted to drylocations where as Type NMC can be used in dry, moist, damp or corrosive environments.
Non-metallic sheathed cable (both Type NM & NMC) is not permitted to be used as a service conductor, in commercial garages, in hoists or cannot be embedded in cement, concrete or aggregate. With minorexceptions use of non-metallic sheathed cable is also prohibited in theaters or any hazardous locations.
NEC Section 336-5 requires that cable be secured in place by suitablemeans so as not to injure the cable. Adequate protection for cable is also required when run is exposed, through joists or rafters, through floors, in unfinished basements and accessible attics.
Cable bends are limited to a minimum of five times the diameter of the cable.
NEC 300-4(b) requires that cable be protected from physical damage whenit passes through factory or field punched, cut or drilled holes in metalmembers. A bushing or grommet firmly secured in place is recommended.

Series 1942Insulated Nipples
Suggested Specifications for Non-Metallic Sheathed Cable Fittings• Where non-metallic sheathed cable or flexible cord terminates
into a threaded or threadless opening, terminating fittings used shall be approved for the purpose by nationally recognized laboratory, inspection agency or product evaluation organization.
• Terminating fittings shall be of malleable iron, steel or thermoplasticconstruction designed to provide adequate strain relief and positivelyprevent damage to jacket or conductor insulation such as series 3300or 3302M manufactured by Thomas & Betts.
Ferrous metal fittings shall be electro zinc plated inside/outsideincluding threads and bushed with a nylon insulated throat.
Thermoplastic material used for connector construction shall be ofhigh impact strength suitable for 105° C/221° F service with a ULflammability rating of 94V-1.
• Where non-metallic sheathed cable passes through either factory or field punched, cut or drilled holes in metallic members, the cable shall be protected by thermoplastic bushing such as series 3210manufactured by Thomas & Betts. Bushing shall be firmly secured in opening. Nylon bushed metallic fittings such as Thomas & Bettsseries 1942 may be substituted as required.

Non-Metallic Sheathed Cable and Flexible Cord Connectors (All Plastic)
Typical Installation
1. Remove sheath from end ofcable (4" or more as required).Insert cable through connectoras shown (Cable under button).
4. Snap connector into knockoutbox. If desired, this step canbe done prior to Step 1.
5. To remove from knockout boxdepress ears.
Application• To connect non-metallic sheathed cable
and flexible cord to a box or an enclosure
Features• Design provides strain relief by partially
deflecting cable (A); therefore:
(1) Connector will not damage outer coveringor jacket of cable, or conductor insulation;designed to give safe trouble free installation
(2) Holding power and cable strain relief are not affected by surface finish of outer covering or cable jacket
(3) Connector provides superior holdingpower far in excess of listing agencyrequirements
• Snap-in one piece design; accommodatesvariation in knockout dimensions, savesinstallation time (B).
• All high-impact thermoplastic construction provides:
(1) Insulated throat; conductors are protected from abrasion
(2) Improved dielectric strength, and eliminates potential shorts
(3) Corrosion resistance
• Wide range — reduces inventories
• Connector may be pre-installed in box K.O. or on cable

2. Insert button into cavity.
3. With grooved pliers, or parallel jawtype pliers (commercially available)squeeze button into cord or wiresas far into connector body aspossible. NOTE: It may be necessary to re-adjust pliers to ensure button is properly installed.
Steel or malleable iron.Two-Screw ConnectorsRounded cable grip and smooth bushing protect the cable sheath and wireinsulation. Because saddle is threaded, screws do not travel or extend beyond the connector body as it is clamped to the cable. An extra lip on the saddle closes the unused part of the connector opening.
• Threaded saddle means screws don’t travel or extend beyondconnector body as it’s clamped to cable
• Extra lip on saddle closes unused part of connector opening
• Steel or malleable iron construction
• Look for the unique T&B blue color ensuring the highest quality fitting
